Worked example: A single filer earning $85,000 in Missouri
Start with $85,000 of wages. After $16,100 in modeled state deductions/exemptions, running it up Missouri's brackets produces about $3,062 in state income tax — an effective state rate near 3.6%, with a 4.7% marginal rate. Federal income tax and FICA are calculated separately and shown in the calculator above.

How Missouri taxes income
Missouri uses a graduated income tax: your income is taxed in slices, with each slice taxed at a higher rate as you move up the brackets from 0% to 4.7%.
Missouri generally starts from your federal income, applies state-specific adjustments and deductions, and then runs the result up the brackets. Credits and exemptions can change the final number — confirm the current details with the Missouri Department of Revenue.

Retirement income & Social Security
Missouri retirement income treatment varies by plan type, your age, and whether the distribution is qualifying. Many states exempt some or all 401(k), IRA and pension income for retirees, and this calculator does not model those exclusions. Check the Missouri Department of Revenue for the rules that apply to you before assuming distributions are taxable.
Local taxes & reciprocity
Kansas City and St. Louis each levy a 1% local earnings tax on residents and on income earned in the city.
Reciprocity: Missouri has no income tax reciprocity agreements. If you work across state lines, you generally file a non-resident return where you work and claim a credit to avoid double taxation.
Notable deductions, credits & other taxes
Deductions & credits
- Missouri standard deduction (about $16,100 single / $32,200 MFJ in this model — verify current amounts)
- Credit for income taxes paid to other states (for residents with out-of-state income)
- State versions of common credits — earned income, child/dependent care, and education credits — where offered
Capital gains: Missouri has no separate capital gains rate. Capital gains included in your federal AGI are taxed as ordinary income at Missouri's graduated rates.
Property tax: Property taxes in Missouri are assessed and collected locally, so effective rates vary widely by county and municipality. Check your county assessor or the Missouri Department of Revenue for local rates.
Missouri vs. neighboring states
Compared with its neighbors — Arkansas, Illinois, Iowa, Kansas — Missouri's graduated rates up to 4.7% sit within the regional range. Effective rates depend heavily on income level, deductions, and local taxes. Note that Tennessee has no income tax at all, which can matter for people living or working near the border.
